Quick Summary
Right now, the Atlantic is quiet. The National Hurricane Center (NHC) predicts no tropical cyclones will develop over the next 7 days (as of 2 p.m. Aug. 17). However, we’re entering the peak of hurricane season (mid-August through mid-October), and forecasters are watching four tropical waves that could potentially develop later.
Important Reminder: "It only takes one" storm hitting your area to make it a bad season for you. Always stay prepared.
Current Atlantic Situation
What’s Happening Right Now
- No active storms in the Atlantic basin
- Four tropical waves being monitored (see details below)
- Strong wind shear + dry air are suppressing storm development
- El Niño continues creating unfavorable conditions across the Atlantic, especially the Caribbean
The Four Tropical Waves Being Watched
| Wave Location | Movement | Speed |
|---|---|---|
| Far eastern Atlantic (south of 19°N) | Westward | 11–17 mph |
| Central Atlantic (near 38°W, 2°N–18°N) | Westward | 17 mph |
| East of Lesser Antilles (near 56°W, south of 18°N) | Westward | 17–23 mph |
| Caribbean (along 75°W, south of 19°N) | Westward | ~17 mph |
What’s a tropical wave? Think of it as a "seedling" — a cluster of showers and thunderstorms that could grow into a tropical storm. About 60 cross the Atlantic each year, but only 10–15% develop. However, they spawn ~80% of major hurricanes!
What’s Coming Next?
Next Named Storm: Dolly
- The 4th named storm of 2026 will be Dolly (pronounced DAH-lee)
- Historically, the 4th storm forms around August 15
- No development expected in the next 7 days, but conditions may improve by late August/September
AccuWeather’s Outlook (Aug. 22–24)
- Low risk for development in an area west of Africa
- This is the Main Development Region (MDR) — where most late-August/September storms form
- Wind shear is expected to decrease as we approach September, giving waves a better chance to survive
Pacific Update: Tropical Storm Lala
While the Atlantic is quiet, the Pacific is active:
- Tropical Storm Lala is moving away from Hawaii
- May regain hurricane strength by August 19
- 126,000+ homes/businesses without power in Hawaii (as of Aug. 17 morning)
- Live updates on Lala
Hurricane Season Basics
When is Hurricane Season?
- Official dates: June 1 – November 30

- Absolute peak: September 10
- Busiest period: Mid-August through mid-October
30-Year Average (1991–2020)
| Storm Type | Average Count |
|---|---|
| Named Storms | 14 |
| Hurricanes | 7 |
| Major Hurricanes (Cat 3+) | 3 |
Major Hurricane = Category 3 or higher (winds ≥ 111 mph)

Key Terms Explained (ELI5)
Tropical Cyclone — The universal term for any organized rotating storm system over tropical waters. Once winds hit 74 mph, it gets a regional name:
- Hurricane — North Atlantic, Central/Eastern North Pacific
- Typhoon — Northwest Pacific
- Cyclone — South Pacific & Indian Ocean
Disturbance — A cluster of storms with some organization but no defined circulation yet. On NHC maps:
- Orange = Medium development chance
- Red = High development chance
- Gray X = Little to no chance (changed from yellow in prior years)
Invest — Short for "investigative area." A system the NHC is studying closely with models and aircraft. Not yet a depression or storm.

FAQ: Your Top Questions Answered
Should I worry since we’re in "peak season" but nothing’s happening?
No panic needed — but don’t let your guard down. The atmosphere is currently hostile to storms (wind shear + dry air + El Niño). However, history shows the peak is coming. Think of it like a loaded spring — quiet now, but potential energy is building.
What’s the deal with "Gulf of America"?
Per a 2025 executive order, U.S. federal agencies (including NOAA/NHC) now use "Gulf of America" instead of "Gulf of Mexico" on maps and in advisories. It’s the same body of water — just a name change on official U.S. products.
If a wave has a "low chance," can it still become a hurricane?
Yes — but it’s unlikely. "Low" typically means <40% chance over 7 days. Most low-chance waves fizzle. But occasionally one beats the odds. That’s why forecasters track them all.
How many storms have hit near my house historically?

What’s the difference between a "tropical wave" and a "disturbance"?
- Tropical wave = A type of disturbance: an elongated area of low pressure moving west with showers/storms. The "seedlings."
- Disturbance = Any suspicious cluster of storms the NHC highlights on the outlook map. All tropical waves are disturbances, but not all disturbances are tropical waves.
